Thats correct, I talked to 2 different techs and they confirm this. The new Vettes, however, DO store calibrations. (thats what they said)

Now that's funny! If u have a dealer who's willing to work w/ you. Otherwise, they'll be...
As far as what the new PCMs store, I remember that thread. But, I also thought the reason that what the PCM stores (or doesn't) regarding reflashes was brought to light by a case in CA. IIRC, the dude had tweaked his ride, & fragged some part(s). GM brought some engineer types in, they looked @ the "black box", & the judge denied the man's claim. GM won. Now, if that's the case, he must not have reflashed before takin back to dealer for service. Thoughts?

I got a 08 CC with a 4.8 Right now its basically stock (tune and longtubes, and a muffler) Im about to turn 6,000 miles, its been a little cooler than normal in the mornings, but I live in south Louisiana so thats about 40* when getting onto the on ramp on my way to work, I notice the 2-3 shift isnt firm, and it over revs a little. Ive fried my share (7+) 4l60e's and one FLT level 5 with the help of a small fluid leak and my 6.0, but I cant believe Ive smoked one on a pretty much stock 4.8 WTF is the deal. These transmissions SUCK. I did ask am ex-Chevy transmission tech and he said it wasnt uncommon while cold, but I still think thats BS. I figured Id have a new trans before 25k miles, but never figured before 10k

I beleive the stock tranny tune lets it slip a little when cold to get it up temp faster.
Don't sell your kids on that, but I think that is the case.
My 07 nnbs did it and my 08 does it, but 4l70e in both cases.

Thanks. I had a tech tell me it wasnt uncommon. Doesnt make me feel all warm and fuzzy inside, but I guess it makes me feel a little more confident it isnt quite ready for the first replacement
